The work reported in this paper concerns the determination of an asymptotic expansion of the electromagnetic field scattered from a convex cylinder near grazing incidence. A systematic procedure for the generation of such an expansion is formulated from the concepts of boundary layer theory. The general form of the mth term in the expansion is derived for all points with a domain that includes the immediate vicinity of the point of grazing incidence and the penumbral region in the neighborhood of the shadow boundary. Boundary and matching conditions for the determination of the unspecified coefficients in the expansion are formulated. Finally, explicit representation for the initial term in the expansion are given for all points within the transitional domain. Author
